To all whom it mag concern: g Be it knownthat I, ALFREn M. LANE, acitizen of the United States, and a resident of the city of St. Louisandv Stateof Miswhich the followingis a specification.

This invention relates to; window-attachments particularly adapted foruseinjmoving .articles or materials into and out of buildings throughthe -windowfopenings therein. The principal object of the presentinvention is to devise a hoisting device which can be readily attachedto and detachedfrom a window without damage thereto and which, when inposition, is capable of supporting a considerable load. Another objectis 'to provide adjustments whereby the device may be attached towindowsof different'sizes and types, struction, reduced cost of 1manufacture, and compactness of design.* The invention consists in thecombinations and ar rangeinents of parts hereinafter described; andclaimed.

,Inzthe accompanying drawing, which forms part of this specification andwherein lilrefl symbols refer to'like parts wherever theyoccur. I V

My hoisting device comprises a metallic bar or beam"10 adapted .tobeplaced hori d i'itis conside r a ALFRED M. LANE, or s'r.

The. rods 11 are provided witli upwardly acurved free end portions18fwhose radius 1 V, "of curvature corresponds substantially. to the Icurvatureiof the grooves thejsash-pulleys. f The beam 10'is attachedito'the window by inserting the" rods 11 "intoft-he' openings locatedbeneath one pair of sash-pulleys 5' around the rear-portions thereof. Bythis with theircurved'end portions disposed in' the grooves of j saidpulleys and hooked .80 arrangement, the-rodsll reston the lowei' edgesof the;openings,in{which the pulleys aremounted and thusserve'to supportthe beam, While theengagement of the curved end portions of the rodswiththe lower rear portions of the pulleys servestoprevent latera1movementof the beam [away from the wil and thus cause transverse tiltingof the bar.

The upper edge of the inner end portion of the beam lS'fOiIllEiCl withteeth 18 which cooperate with corresponding teeth 19 formedin theuppersurface of the opening that extends through the slide 15. This openinghas a greater vertical dimension than the vertical dimension of the:bar,

whereby the slide may be moved upwardly I a distance siitlicie 'itv tocause the teeth of the slide and the bar 'to become disengaged. The cooperative'teeth of the bar and slide are shaped like those of a saw andare. ar-

anged sons to resist movement of the slide away from the window whilepermitting the slide to be slid into. engagement therewith. Theadjustable slide l lispr'ovided in its" bottom with an upwardly bowedleaf spring 20 which bearsagainst the under side of the hanger bar andthereby tends to hold the teeth of the bar and the adjustable slide inengagement with each other.

The articles or materials that are tobe hoisted or lowered are suspended from the outer end of the beam by arope (not shown) that passes through a block 2% having a swivelconnection 23with a supporting hook 25'adapted to be mounted in any oneof a series of. holes 26 provided therefor in the outer endof the beam.v 7

' it is obvious, from the foregoing description that my hoisting deviceis very. simple in construction, that it can be readily attached to anddetached from a window, that it is capable of'supp'orting a considerableload, and that it can 'be adjusted. to. fit windows of differentsizcs'and types.
